By tracking guns and who they are sold to, that will only help you track the guns that are legally sold. School mass murders are usually not done by the people who legally buy the guns since... they usually are not old enough to buy them. Obviously in cases like VT, you may have someone old enough to buy it but tracking who bought the gun is not going to help you stop them from shooting someone. Ill give you an extremely liberal website to look at... http://www.huffingtonpost.com/josh-sugarmann/killings-by-concealed-han_b_471765.html Now look at those numbers... 139 people killed by CCW holders in 3 years. Now... That is less that the number of people killed by only handguns in Alabama in just 2009. http://www2.fbi.gov/ucr/cius2009/data/table_20.html So you really mean to tell me the problem is CCW holders?
